Comparing: AT 2 vs. Pz.Sfl. IVc vs. SU-85

Design for an assault tank to break through enemy defensive lines. The design was completed by May 15th, 1943. No prototypes were built, the project helped set the stage for another heavy assault tank, the A39 Tortoise.

Proposed antiaircraft vehicle mounting the 88-mm antiaircraft gun. Development started in Germany in 1941. The vehicle was based on the Pz.Sfl.IVc chassis. The operational requirements for the vehicle were constantly changed, and the FlaK 41 gun was mounted on the chassis only in 1944. The vehicle was to be the basis of variants with other armament alternatives. However, the plan was never implemented. Only three prototypes were manufactured.

Developed on the basis of the T-34 medium tank and the SU-122 assault gun. Produced from August 1943 through July 1944. The 85-mm D-5S gun allowed the SU-85 to effectively hit enemy medium tanks at distances of more than 1,000 meters and to penetrate the front armor of heavy tanks at shorter distances.
